Granted: 1991-10-01
Abstract: Abstract of Disclosure A tensioner is provided with a female screw member for the tension adjustment of a belt or  a chain screwed with a male screw provided a rotation force by a spring and a bearing in which the female screw member is inserted and constrains the rotation of the female screw member.    In this tensioner, an outer form of the  female screw member is formed so as to correspond to a bearing hole of the bearing.  By this, an approximately whole length of the female screw member is able to slide through the bearing hole, and the stroke length of the female member can be secured sufficiently even if the size of the device in a tension controlling direction is shortened.

Abstract: Abstract An RF power supply serves to supply a regulated power amplified RF drive signal to an RF transmitter.  The supply includes an RF oscillator for providing an RF input signal.          A DC voltage source provides a DC voltage V.  A plurality of power amplifiers are provided with each receiving the input RF signal and each having an input for receiving a DC voltage signal, and each serving to amplify the input RF signal by an amount dependent upon the magnitude of the DC voltage signal supplied to its input and thereby provide an amplified RF signal.  The amplified RF signals are combined to provide an RF drive signal.  The DC voltage V is directly supplied to the input of at least a first one of the power amplifiers.  A regulating means serves to regulate the magnitude of the RF drive signal with the regulating means including circuitry for applying a fractional portion of the DC voltage V to the input of at least a second one of the power amplifiers with the fractional portion varying as a function of any variation in the magnitude of the DC drive signal with respect to a desired magnitude thereof.

Patent NL-32365-C (NL)
IPC: C06B21/00
Abstract: Trinitrotoluene, completely or nearly free from mineral acids, is purified by treating it in the molten state at or about its solidifaction point and preferably not above 83 DEG  C., with a dilute aqueous solution of an alkali sulphite such as sodium sulphite in the presence of a weakly acidic substance or mixture of substances in quantity at least sufficient to maintain an appreciably steady hydrogen ion concentration throughout the treatment, the initial hydrogen ion concentration of the aqueous solution lying between pH 7,0 and 8,3.  Suitable weakly acidic solutions are a mixture of sodium acetate and acetic acid, sodium mono hydrogen phosphate and sodium dihydrogen phosphate, boric acid alone or where the crude trinitrotoluene contains a little residual acid boric acid mixed with sodium borate, ammonium bicarbonate or sodium bicarbonate.  In an example molten crude trinitrotoluene, previously washed with water until practically free from mineral acid, is stirred with an aqueous solution of sodium sulphite, sodium monohydrogen phosphate and sodium dihydrogen phosphate.  The mixture is allowed to settle and the separated trinitrotoluene is treated with a further amount of the aqueous solution, separated and washed.  The process may be carried out continuously.
